RTTY Loop from page J 8

Lei's bop out of converter building long enough to consider a question sent in by Bob Bunn WAOLKE. Bob writes ihal he is setting up his RTTY station, but that a German amateur tofd him that this equipment operates on 170-Hz shift™ using tones of 1275 Hz and 1445 Hz. He wants to Know how to buyt build, or modify a terminal unit to work the DA on these frequencies.

WeiBobt it all boils down to what you will be receiving. As we have stated here before, put AFSK into an SSB rig and FSK comes out. That is, it does not matter what frequency tones the DX station feeds into his transmitter; all you will see is plain old 170-Hz shift FSK RTTY. What frequency audio tones you recover depends only on your receiver. Any converter that works on anyone else would work on him. Okay?

Those of you in the rnid*At* iantic area, be sure to come to Baltimore on March 30, 1980, for the Greater Baltimore Hambor-ee and Computer lest. Sponsored by the Baltimore Amateur Radio Club and Calvert Hall, it promises to be a whale of an event, with good oV NSD, himself, speaking. I will be there, too, so hope to see you there.
